By the essence of a person, I, first of all, mean his potential - what a person can realize in life. Or maybe not. For example, an infant can potentially learn to talk and walk. But if he does not learn this, then this potential will not be realized. With children, however, everything is clear. We have tables where it is written what and at what age a child should master with normal development. We will not discuss the adequacy of such tables - they, at least, are.
With adults, everything is more complicated. There are no tables for them, but the huge difference between people suggests that not everyone has fully manifested his human essence, has reached personal maturity, and has realized his potential. Our trouble is that the human essence is not at all obvious, it does not reveal itself and is not realized by itself. The possibility of this realization in many respects directly depends on the person himself - on how he understands this task, and his efforts. And the main question is what is considered human potential?
For example, a kitten will grow into a cat, and a rose sprout will grow into a rose bush, in any case, without any efforts of its own or from outside. If the conditions are bad, then the cat or the rose may be weak, sick, but their essence will not change from this. But a person does not always even guess his potential. And this can happen just because he understands his essence in such a way that he does not take into account many of the possibilities of this potential. These opportunities have not gone anywhere, but a person does not give them development. As a result, an internal conflict arises, which secretly spoils his life. And he cannot understand what is the matter
